Self-organization of the magnetization in ferromagnetic nanowires

Ivanov, A. A.; Orlov, V. A. JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS, 440 217-220; Doi: 10.1016/j.jmmm.2016.12.053 OCT 15 2017

In this work we demonstrate the occurrence of the characteristic spatial scale in the distribution of magnetization unrelated to the domain wall or crystallite size with using computer simulation of magnetization in a polycrystalline ferromagnetic nanowire. This is the stochastic domain size. We show that this length is included in the spectral density of the pinning force of domain wall on inhomogeneities of the crystallographic anisotropy. The constant and distribution of easy axes directions of the effective anisotropy of stochastic domain, are analytically calculated.
